The Betta Fish is among the most popular home aquarium pets. Its scientific name is Betta splendens and is also known as the Siamese fighting fish. The Bettas Domain is Eukarya, Kingdom is Animalia, Phylum is Chordata, Class is Actinopterygii, Order is Perciformes, and Family is Osphronemidae. The average betta is 7.5 centimeters in length. Its body shape is streamlined, allowing it to effortlessly swim through open water. The Bettas body is covered with scales that overlap each other, kind of like shingles on the roof of a house. The scales consist of thin, transparent plates that protect the body of the betta and add streamlining for gliding. There is a mucus layer that covers the scales of the fish to protect against parasites and infections. …show more content…
Betta live in thickly overgrown ponds and are found in only slowly flowing waters such as stagnant pools, polluted streams, and other types of areas with the water having low-oxygen content. Bettas mainly feed on insects that fall into the water and on zooplankton, crustaceans, and the larvae of mosquitoes. Bettas have a rapid metabolic rate making them in need to eat frequent small snacks, such as algae. Bettas are a smaller fish and are lower on the food chain. Just above insect larvae and below larger predatory fish and birds. The betta can be found worldwide in pet stores since it is a domesticated fish, but it can be found naturally swimming among the native waters of Thailand. The question we are asking is, What kind of objects can cause the betta to become aggressive and flare up? Are hypothesis being If we expose a male betta fish to another male betta fish, female betta fish, mirror, and other objects resembling a male betta fish his instinctive behavior will cause him to flare up. The independent variable of our experiment is the time between showing the male betta the testable objects. The dependent variable of our experiment is the reaction and action of the betta fish once it is shown one of the
To begin the lab, the variable treatment was prepared as the Loggerlite probe, used to later measure oxygen consumption, warmed up for approximately 10 minutes. To prepare the variable treatment, 200ml of Sodium and Ammo-lock water was measured in a container and a pre-prepared “tea bag” of tobacco was steeped in the room temperature treated water until a light yellow color was visible. After preparing the tobacco solution the preparation for the live goldfish began as two beakers were filled with 100 ml of treated water. Each beaker was weighed before addi...

The nonnative species of the lionfish, living in tropical waters to depths far below is an unseen threat by first glance. Truth behold, this fish is a serious pest since the first sighting in Dania Beach back in the 1980s. Presently, it has grown out of its bounds and causes harm not only to the sea life but trouble to humans as well. An unmatched appetite with a fast and large reproduction to spawn its species in a matter of only a short time, makes this invasive fish at the top of a sounding alarm. Clever biological adaptations have made this fish a tough fighter to the ecosystem and only in the past few years have we learned to take effective measures to control their population to save our coral reefs.

Venus flytrap is a carnivorous plant native in bogs and swamp lands in North and South Carolina. It was discovered in the 1700s and named after the Greek goddess Dione which gave it the scientific name Dionaea. The species name muscipula came from the Latin word “Mus” (mouse) and “Cipula” (trap). Venus flytrap is one of the only two known species of plants that use fast-closing, double-spaced trap mechanism to capture insects.
Scorpaenidae are mostly marine fish,very few found in fresh and brackish water. The family have around around 45 different genera and 380 different species. They are mostly found in the India Ocean and the Pacific Ocean. Most of them lives in coral, tropical reefs and shallow waters, warmer areas. Not all of the family fish lives in the shallow water, small portion of the Scorpaenidae live deep as around 7,000 feet. Just like most of the coral reef fish are, Scorpaenidae have camouflaged body. Their characteristic reflects their name, they have sharp spine that can sting other organisms. Their spine are covered with venomous mucus just like how some other kind of fish are covered with the venomous mucus. Their body are covered with scales. Generally speaking, the Scorpaenidae family fish have different number of spines over the course of the body. Most known type pf Scorpaenidae are lionfish and scorpionfish. Lionfish have preorbital bone with 3 spines, spines and third below the diagonal; , big mouth, end position, oblique fissure. Mandible, vomer and jaw bone with villiform teeth group. Gill openings are wide, tetrabranchiate membranes without the isthmus, pre-opercular margin with 5 spines. Body are ctenoid scales, round head. On the side, there are about eight to nine dorsal fin, fin spines and rays of an anal fin; five to six pectoral fins, they are large, round, and are branched from the upper fin rays. There are about one to five pelvic, sub thoracic; caudal fin rounded truncate. Reef stonefish are extremely camouflaged, they could look exactly like a rock when hiding for predation. The spines of Scorpaenidae are hard and rough, some of their fin spines have poison, can cause serious pain, swells and fatal wounds. Some of ...
If puffins are disturbed by humans they will leave their nests and will not come back. This has led to the extinction of puffin colonies in parts of the European coastline.
In this study, we analyze aggression in crayfish, because they are known to fight with each other, and they have a distinct ethogram from which to compare and contrast all of their behaviors (Moore 2007 and Wofford 2013). We seek to find out the affect of sex on agonistic interactions, and whether different ratios of between-gender interactions affect levels of aggression. It has been previously observed that male crayfish are usually dominant over females (Moore 2007). Additionally, male-male agonism is generally the most intense, while male-female and female-male interactions are less intense (Moore 2007). Since males are more aggressive than females, and male-male interactions are the most intense, we hypothesize that aggression levels vary by sex when fighting in groups of differing sexual ratios. Will males be less aggressive when outnumbered by females? Similarly, will males be more ag...
1996). A study was done to examine the different parent-juvenile interactions of two different species of poeciliids: P. Monacha and P. Lucida. Individual females of the two species were place into chambers that had a mesh net to segregate it and allow juveniles to swim through and escape attack from the parent. The females were kept in these chambers as they birthed offspring and were recorded. It was found that the p. monacha females cannibalised their offspring immediately while the p. lucida females did not (Thibault 1974). The p. monacha juveniles that did escape the initial attack, swum to the bottom and through the mesh net. However, the juvenile p. lucida remained in the same section of the chamber with the female near the water
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.
The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.
Just as in any other sport, understanding gives rise to advantage and success. As serious fishermen, we had dedicated much thought to understanding the fish, hypothesizing their behavior. One understanding we had already gained through previous experiences was that fish readily eat the prey that is normally available. This, we concluded, was a sort of defense against fishermen and their foreign lures and was acquired through the fishes’ own previous experience of eating a lure. In applying this understanding to our fishing, we performed a routine food chain analysis to find out what our lures needed to imitate. The results were that the part of the food chain just beneath our quarry consisted mostly of small fish such as anchovies and young yellowtail, smaller than those shad and bluegill normally eaten in freshwater ponds. To compensate for this difference we would have to use lures smaller than those we were used to using. Luckily we had some.
The purpose of this lab was to study the response of the genus Daphnia to chemical stimuli and to examine human responses to different stimuli. A stimulus is an incentive; it is the cause of a physical response. Stimuli can have a physical or chemical change; an example of a physical change is a change in temperature and sound. An example of chemical change would be changes in hormone levels and pH levels. Muscular activity or glandular secretions are responses that occurs when stimulus information effects the nervous and/or hormone system. Daphnia is a genus; it is a small crustacean that lives in fresh water. The body of the daphnia is visible and its internal organs are clearly seen thus it was chosen for this exercise. The
